Answer:
x = 13/4
Step-by-step explanation:
(2x/3)-(5/3)=(1/2)
Multiply everything by 3
2x - 5 = 3/2
Get the x term on it's own by adding 5 to both sides
2x = 3/2 + 5
2x = 3/2 + 10/2
2x = 13/2
Divide by 2 to get x on it's own
x = 13/2 ÷ 2 = 13/2 * 1/2 = 13/4
Ill assume it is
If we multiply each term by the LCD of 6 and 8 ( ie 24) we get
4b + 3(b + 2) >= -15
7b >= -15-6 = -21
b >- =21/7
b >= -3
Its D
You would have to find the surface areas of each box, which would be 8*4 *2, 8*3 *2, and 4*3 *2. That *3, would be the cost, and then surface area of 2 would be 12*4 *2, 12*2 *2, and 2*4 *2. That *3 would again be the cost to make the box. That all would be A=64 + 48 + 24, or 136*3 = $408 to make box A, and box B=96 + 48 + 16 = 160*3 = $480 to make box B. Therefore, box B, or $480 - $408 = $72 more.
The two integers is -3 and -4
